The Air Shower Pass Box is a cleanroom transfer device. Its function is to decontaminate the surface of items before they are transferred into the clean environment, so as to prevent impurities from damaging the clean environment.It can use clean, high-speed, unidirectional airflow to flush items, combined with an interlocking system and integrated control panel, to ultimately ensure the safe and low-risk transfer of items and maintain the integrity of the cleanroom.
Our engineers develop tailored air shower pass box solutions with high‑velocity jets and HEPA filtration to remove particles at the transfer point and safeguard your cleanroom.
Air Shower Pass Box
Adds “active cleaning” at the transfer point: high‑velocity jets of HEPA‑filtered air blow particles off cartons, tools, and components before they enter the cleanroom.
Best for higher‑risk areas or higher cleanroom grades where what’s sitting on the surface of the material really matters (aseptic pharma, biotech, micro‑electronics).
Helps cut down on hidden contamination that can slip through a regular pass box when items come from lower‑grade or uncontrolled areas.
Does cost more and uses more energy than a simple pass box, but pays off when your risk assessment shows surface particles are a real problem.
Needs proper setup and routine checks (air velocity, filter integrity, cycle time) so the air shower cycle actually performs as intended.
Regular Pass Box
Acts mainly as a physical barrier: a sealed transfer chamber with interlocking doors to stop people walking in and out and to reduce air exchange between rooms.
Ideal for lower‑risk transfers or where materials are already reasonably clean and you just want to avoid opening doors directly between areas.
Simpler and cheaper to buy, install, and validate compared with an air shower design, with fewer moving parts and controls.
Often chosen after a risk assessment shows that basic separation and door interlock are enough to protect the process and environment.
Easier to maintain day‑to‑day: focus is on door interlocks, seals, and cleaning, rather than air velocities and complex filtration performance.
Tough on sterility and cross‑contamination? Deiiang Air Shower Pass Box protects material transfer as a final “airlock”, helping you pass new GMP and audits with fewer worries.
Multi‑grade cleanrooms, tight contamination limits. Deiiang Air Shower Pass Box cuts personnel traffic, cleans materials with focused air, and supports traceable, compliant CGT production.
SPF rooms fear incoming microbes. Deiiang Air Shower Pass Box “air‑washes” feed, cages, and tools at transfer, helping you keep the barrier tight with less manual intervention.
Even sub‑micron particles kill yield. Deiiang Air Shower Pass Box delivers high‑velocity, targeted air during cross‑bay transfers, helping you reduce defects and yield variation.
Dust means bright dots and scratches. Deiiang Air Shower Pass Box gives glass and optical parts a “second cleaning” during transfer, cutting defects and rework in critical lines.
Tiny particles cause big failures. Deiiang Air Shower Pass Box air‑cleans trays and components before assembly zones, helping you protect reliability and reduce field returns.
Shared labs struggle with cross‑contamination. Deiiang Air Shower Pass Box cleans samples and reagents as they move between rooms, making it easier to meet method and accreditation requirements.

An Air Shower Pass Box is a specialized equipment used in cleanroom environments to facilitate the transfer of materials while minimizing contamination. It features a chamber where items are passed through, and air showers—high-velocity jets of filtered air—blast the surfaces of the items to remove any particulate contaminants before they enter the cleanroom. This process helps maintain the integrity of the controlled environment by preventing the introduction of foreign particles.

The Air Shower Pass Box is a transfer device designed to decontaminate items. Before items are transferred between two areas with differing cleanliness levels, high-speed jets of HEPA-filtered air are directed at their surfaces to blow away particulate matter and contaminants.
In practical applications, the Air Shower Pass Box can reduce the load on HVAC systems by lowering particle counts, while simultaneously reducing the risk of contamination in the cleanroom. Ultimately it helps ensure that the environment complies with ISO 14644 cleanroom standards and relevant GMP requirements.
Air Shower Pass Boxes are commonly used in pharmaceutical and biotechnology factories, hospital pharmacies, medical device manufacturing workshops, the food and beverage industry, the electronics and semiconductor industry, and university laboratories.
The Air Shower Pass Box is a common and cost-effective device for any application where you want to deliver materials into a clean environment that meets ISO standards.
The Air Shower Pass Box draws in air and then sprays filtered clean air at high speed through nozzles to disinfect and decontaminate the surfaces of the items being transported. The air velocity is usually set between 20 and 25 m/s, a value that meets the reference standards in many cleanroom air shower design guidelines.
During the decontamination process, the entrance and exit doors will be kept closed to prevent danger and contamination. After disinfection is complete, the exit door will unlock automatically. At this point, the number of particles attached to the surface of the items has been greatly reduced, meeting the standard for entry into the clean area.
First, you need to consider the following three questions:
What are the maximum dimensions and weight of the item you are sending? What is your transmission frequency? How much wall space and hallway width do you have, and how much space can you leave to install a pass box?
Small Air Shower Pass Boxes are ideal for passing laboratory bottles and small containers; medium-sized Air Shower Pass Boxes are suitable for hospital/pharmaceutical packaging areas; and large Air Shower Pass Boxes are suitable for heavy equipment, pallets, or high-volume plants.
For most pharmaceutical, medical device, and electronic applications, equipping the pass box with a HEPA H13/H14 grade filter is perfectly adequate. However, if you need to use it in a high-level clean area, you can consider choosing an ULPA filter to further reduce ultrafine particles.
Yes. Our modern Air Shower Pass Box can provide signals to your BMS and access control system, allowing you to more easily monitor the status of the pass box door, the fan, and alarm status.
This integration approach is becoming increasingly common in GMP and ISO compliant facility designs because it reduces operational errors and provides more comprehensive event logging.
To size and configure an Air Shower Pass Box correctly, you should prepare:
Layout drawing and wall thickness; cleanroom and support area ISO/GMP class; all material compatibility requirements (e.g., stainless steel grade, glass, special seals); and integration requirements, for example the integration of building management systems (BMS), access control systems, and data logging.
With this information, we can provide you with a customized Air Shower Pass Box solution, including technical drawings and specifications, and assist you in planning the installation.
